All you need in this life is ignorance and confidence, and then success is sure.?

Samuel Langhorne Clemens aka mark twain means that if you are confident in your ability to do something no matter the odds against you. That you will be successful. And he means by being ignorant he means if you don't know that the things you are trying to accomplish is not accomplishable then you want give up or trick yourself to think its not possible. For example the Wright brothers who were the first to fly. Imagine if they believed and understood that man cant fly as people were thinking before that. Since they were ignorant to that fact man cant fly it doesn't apply to them. Another example is lets say your mom doesn't want you get a tattoo so you get one but never tell her so she still thinks you don’t have one and she is still as happy as when you didn't have one. Ignorance is bliss knowledge makes you nuts. Another example is if you know what the government was doing you would be to would be nuts.
